[1][2] Singer, guitarist and main songwriter Mark Kjeldsen, drummer Bobby Irwin and bassist Ron François first played together in a London R&B band called The Strutters.
[3] Keyboardist Don Snow joined them in support of the record on the 1978 "Be Stiff" Tour, thus completing the Sinceros line-up.
Undeterred, the band continued to accept studio session work with other artists, with Irwin and Snow particularly in demand (both would later play with Van Morrison).
Several FM radio recordings of the band circulate, notably one from 13 December 1979 at The Palladium in New York City, that was broadcast by WNEW-FM.
Dubbed the "$5 Rock and Roll Show", the bill also featured Bruce Woolley, Paul Collins' Beat and 20/20 and was attended by Mick Jagger.
A live album featuring Kjeldsen on rhythm guitar was recorded at the Winterthur, Switzerland, on 10 August 1982 and released in 1983.
François joined The Teardrop Explodes and stayed with Epic Records releasing a solo single, "If You Love Me", in 1982 before departing to live in Australia where he has worked with local artists such as James Reyne, Wendy Matthews and The Eurogliders.
